Recently, an artificial intelligence (AI) system that implements human-level intelligence has been used in various fields. Unlike an existing rule-based smart system, the AI system is a system that trains itself autonomously, makes decisions, and becomes increasingly smarter. The more the AI system is used, the more the recognition rate of the AI system may be improved and the AI system may more accurately understand a user preference, and thus, an existing rule-based smart system is being gradually replaced by a deep learning based AI system.

AI technology refers to machine learning (deep learning) and element technologies that utilize the machine learning.

Machine learning may be an algorithm technology that classifies/learns the features of input data autonomously. Element technology may be a technology that simulates functions of human brain such as recognition and judgment by utilizing machine learning algorithm such as deep learning and consists of technical fields such as linguistic understanding, visual comprehension, reasoning/prediction, knowledge representation, and motion control.

AI technology may be applied to various fields as follows. Linguistic understanding may refer to a technology to recognize and apply/process human language/characters and includes natural language processing, machine translation, dialogue systems, query response, speech recognition/synthesis, and the like. Visual comprehension may refer to a technology to recognize and process objects like human vision and includes object recognition, object tracking, image search, human recognition, scene understanding, spatial understanding, image enhancement, and the like. Reasoning prediction may refer to a technology to acquire and logically infer and predict information and includes knowledge/probability based reasoning, optimization prediction, preference based planning, recommendation, and the like. Knowledge representation may refer to a technology to automate human experience information into knowledge data and includes knowledge building (data generation/classification), knowledge management (data utilization), and the like. Motion control may refer to a technology to control autonomous traveling of a vehicle and motion of a robot, and includes motion control (navigation, collision avoidance, and traveling), operation control (behavior control), etc.

Recently, for the efficient management of information and various user experiences, a voice-based AI personal assistant platform has been provided on an electronic apparatus. The electronic apparatus might support a natural and interactive interface to a user through the personal assistant platform.

For example, when the user requests to make a call while referring to a name of a specific counterpart, an AI personal assistant of the electronic apparatus may find a phone number corresponding to the name of the counterpart from previously stored contact information and connect the user with the counterpart. However, in order to use this function, the user must correctly remember the stored name of the counterpart. When the user attempts to contact with a name different from the stored name of the counterpart, there is a problem in that the contact fails.

The sound outputter 160 may include various sound output circuitry and output an audio signal. For example, the sound outputter 160 may output the voice of the counterpart received through the communicator 110. In addition, the sound outputter 160 may output audio data stored in the memory 120. For example, the sound outputter 160 may output various notification sounds and may output voice of an AI assistant. The sound outputter 160 may include, for example, and without limitation, a receiver, a speaker, a buzzer, etc.

The display 170 may be a configuration to output an image. The display 170 may be implemented as, for example, and without limitation, a liquid crystal display (LCD), a light-emitting diode (LED) display, an organic light-emitting diode (OLED) display (e.g., active-matrix organic light-emitting diode (AMOLED), passive-matrix OLED (PMOLED), or a microelectromechanical system (MEMS) display, an electronic paper display, or the like. The display 170 and the touch sensor of the inputter 150 may be implemented as a touch screen by forming a mutual layer structure.

The memory 120 may store computer executable instructions, and when the computer executable instructions are executed by the processor 130, a control method of the electronic apparatus 100 described in the disclosure may be performed.

For example, the processor 130 may execute the computer executable instructions to control the electronic apparatus to obtain a name referring to a user of another electronic apparatus in a chat with the user of the other electronic apparatus using the AI intelligence model trained by the AI algorithm and store the obtained name in the memory 120 in association with contact information of the user of the other electronic apparatus while performing the chat with the user of the other electronic apparatus through the communicator 110.

In addition, the processor 130 may execute the computer executable instructions to control the electronic apparatus to obtain the name referring to the user of the other electronic apparatus in a voice chat using the AI model while the voice chat is performed through the microphone 140.

In addition, when a user voice for making a call including the obtained name is input through the microphone 140, the processor 130 may control the electronic apparatus to perform a call connection based on the contact information of the user of the other electronic apparatus.

In addition, the processor 140 may provide various UIs through the display 170. For example, the processor 140 may provide a UI for a chat, a UI for inquiring whether to perform the call connection, a contact information UI, etc. through the display 170.

FIG. 4 is a flowchart illustrating an example method of controlling the electronic apparatus 100 according to an embodiment of the disclosure.

Referring to FIG. 4, while conducting a chat with a user of another electronic apparatus using the electronic apparatus 100, a name referring to the user of the other electronic apparatus is obtained in the chat with the user of the other electronic apparatus using an AI model trained by an AI algorithm (S410).

In addition to a name referring to a counterpart, various kinds of meaningful information such as a keyword indicating a relationship with the counterpart, an address of the counterpart in the chat, schedule information related to the counterpart in the chat, etc. may be obtained in the chat.

The electronic apparatus 100 may support a text chat function and a voice chat function, and may obtain meaningful information using the AI model in the text chat and the voice chat.

The electronic apparatus 100 may obtain and understand meaningful information in text using the AI model for natural language processing (NLP). When a voice is input, the electronic apparatus 100 may use speech to text (STT) technology that first converts the voice into text. The AI model for analyzing a chat with the counterpart may be provided in the electronic apparatus 100 by itself, or the AI model may be provided in an external server such that the electronic apparatus 100 transmits the chat to the external server and is provided with an analysis result of the chat from the external server. Some processes of chat analysis may be performed in the electronic apparatus 100 and another process may be performed in the external server. For example, the electronic apparatus 100 may transmit the voice chat to the external server, and the external server may convert the voice into text and provide the text to the electronic apparatus 100, and the electronic apparatus 100 may perform NLP on the converted text.

The text chat may be performed through, for example, a message application. The message application may be installed in the electronic apparatus 100 or may include a message application (e.g., KakaoTalk™, Line™, WhatsApp™, etc.) downloaded from an application store such as Google Play™ or Samsung Apps™. The text chat may be in various forms such as, for example, and without limitation, SMS, MMS, email, etc.

The electronic apparatus 100 may provide a chat UI for conducting the chat with the user of the other electronic apparatus. The chat UI may be provided by executing the message application, and may include a region in which a chat text is input and a region on which a chat input by oneself and a chat input by the counterpart are displayed. For example, the electronic apparatus 100 may provide a chat UI 10 as illustrated in FIG. 1.

The electronic apparatus 100 may obtain meaningful information such as a name referring to a user of another electronic apparatus, a relationship, an address, etc. in a chat input through the chat UI using the AI model. For example, the electronic apparatus 100 may obtain “bulldog” which is a name referring to “Hong Gil-Dong” that is a counterpart in the chat input to the chat UI 10 of FIG. 1.

The voice chat may be performed through, for example, and without limitation, a general phone, a Voice over Internet Protocol (VoIP) based Internet phone (e.g., Skype™, FaceTime™, etc.), or the like.

The electronic apparatus 100 may obtain meaningful information such as the name referring to the user of the other electronic apparatus, the relationship, the address, etc. in the voice chat using the AI model while the voice chat is performed with the user of the other electronic apparatus. For example, the electronic apparatus 100 may obtain the name referring to the user of the other electronic apparatus by converting the voice chat into text and inputting the converted text into the AI model, using the AI model.

When a first name is previously registered in contact information of the user of the other electronic apparatus, the electronic apparatus 100 may use the AI model to obtain a second name different from the first name in the chat with the user of the other electronic apparatus. That is, a name different from a previously stored name is obtained. When there is no previously registered name, a new name may be obtained in the chat.

When the name is obtained, the electronic apparatus 100 may store the obtained name in association with the contact information of the user of the other electronic apparatus (420). For example, as described with reference to FIG. 1, a bulldog indicating Hong Gil-Dong in a chat with Hong Gil-Dong may be stored in association with contact information of Hong Gil-Dong. In addition to the name of the counterpart, when a variety of meaningful information such as a keyword indicating the relationship with the counterpart, the address of the counterpart, etc. is obtained in the chat, this may be stored in association with the contact information.

When the name referring to the user of the other electronic apparatus is obtained more than a predetermined number of times in the chat with the user of the other electronic apparatus, the electronic apparatus 100 may store the name in association with the contact information of the user of the other electronic apparatus. For example, it may be determined that the name refers to the counterpart only when the name is used repeatedly more than a predetermined number of times.

When a user input for viewing a contact of the counterpart is received, the electronic apparatus 100 may provide a contact information user interface (UI) including a phone number of the counterpart and names referring to the counterpart. For example, when the user input for viewing the contact of the counterpart is received, the electronic apparatus 100 may provide a contact information UI 20 including the name of the counterpart ‘Hong Gil-Dong’, a phone number ‘010-0000-0000’, a nickname ‘bulldog’, etc. as illustrated in FIG. 1.

Functions that may be performed using the name ‘Hong Gil-Dong’ which is previously registered in the contact information may be performed in the same manner using ‘bulldog’ which is another name obtained through the chat. According to an embodiment, the name obtained in the chat may be used for a dialing function.

FIG. 5 is a diagram illustrating an example embodiment of the disclosure in which a name of a counterpart obtained in a chat is utilized in a dialing function.

Referring to FIG. 5, when a voice of “Call Bulldog” is input from a user, the electronic apparatus 100 may search for Bulldog in all contact names and nickname items and perform a call connection based on contact information of Hong Gil-Dong having a nickname as the bulldog.

Because an AI assistant of the related art performs a call connection function only based on a stored name, when the voice of “Call Bulldog” is input, the call connection fails, whereas according to an embodiment of the disclosure, the call connection may be successful.

Instead of making a call immediately, the call may be performed after it is confirmed from the user. For example, when a user voice for making a call including the name obtained through the chat is input, the electronic apparatus 100 may provide a message UI inquiring whether to perform the call connection to a previously registered counterpart with another name. An embodiment related to this example will be described in greater detail below with reference to FIG. 6.

FIG. 6 is a diagram illustrating another example embodiment of the disclosure related to a dialing function.

Referring to FIG. 6, when a voice of “Call Bulldog” is input from a user, an AI assistant of the electronic apparatus 100 may provide a message UI 610 inquiring whether to perform a call connection to another name registered in contact information associated with the bulldog, i.e. “Hong Gil-Dong”. When a voice, for example, “yes”, that the user agrees with the message UI 610 is input, the electronic apparatus 100 may perform the call connection based on the contact information of Hong Gil-Dong corresponding to the bulldog. When a voice, for example “no”, that the user does not agree with the message UI 610 is input, the electronic apparatus 100 may not perform the call connection.

A name referring to a counterpart obtained through a chat may be used in a message sending function in addition to the dialing function. For example, when a voice, “Text Bulldog to meet at the park today” is input from the user, the electronic apparatus 100 may find a contact of Hong Gil-Dong corresponding to Bulldog and transmit a message “Meet at the park today” to the contact.

FIG. 7 is a diagram illustrating another example embodiment of the disclosure related to a message sending function.

The electronic apparatus 100 may transmit a message using a name obtained in a chat with a user of another electronic apparatus. For example, when a user voice including the obtained name for transmitting the message is input, the electronic apparatus 100 may transmit the message including the name in the beginning based on contact information of the user of the other electronic apparatus.

For example, referring to FIG. 7, when a voice “Send text message to Hong Gil-Dong to meet at the park today” is input from a user, because the electronic apparatus 100 has obtained ‘bulldog’ in a usual chat with Hong Gil-Dong and stored it in contact information of Hong Gil-Dong, the electronic apparatus 100 may transmit a message including ‘bulldog’, a nickname obtained in a contact of Hong Gil-Dong in the beginning of the message. For example, as illustrated in FIG. 7, the electronic apparatus 100 may transmit the message “Bulldog, meet at the park today”. According to the embodiment, there is an advantage in that a message may be transmitted while calling a counterpart by a name commonly used in the usual chat.

The same name may be used to refer to multiple persons. For example, a name stored in association with contact information of a first user of another electronic apparatus and a name stored in association with contact information of a second user of another electronic apparatus may be the same.

FIG. 8 is a diagram illustrating an example embodiment of the disclosure in which a call connection is performed when the same name is used to refer to multiple counterparts.

Referring to FIG. 8, in case where a name “Honey” is stored in association with two pieces of contact information, when a voice “Call Honey” is received from a user, the electronic apparatus 100 may provide a UI 810 indicating that there are a plurality of contacts having “Honey”. When the user utters a voice selecting one of the plurality of contacts, for example, “Call Jane”, the electronic apparatus 100 may perform the call connection based on a contact of Jane.

According to another embodiment of the disclosure, when the same name is stored in a plurality of contact information, the plurality of contact information may be prioritized and used based on a frequency of use of the name.

For example, the electronic apparatus 100 may store a frequency of use of a name referring to a user of another electronic apparatus in a chat. For example, a frequency of use of a name referring to a first user and a frequency of a use of a name referring to a second user may be stored. When a user voice for making a call including the name is input, the electronic apparatus 100 may perform a call connection based on contact information of a user having a higher frequency of use of the name. An example embodiment in this regard will be described in greater detail below with reference to FIG. 9.

Referring to FIG. 9, when a voice of “Call Honey” is received from a user, the electronic apparatus 100 searches for contact information of a person who has “Honey”, and when there are a plurality of found contact information, may make a call connection based on contact information of a person with the highest frequency of use of the name “Honey”. In this example, a UI 910 may be provided for guiding that the call connection is performed on the contact information of the person with the highest frequency.

On the other hand, because a person may be called by various nicknames, two or more nicknames may be stored in contact information.

Not only a name referring to a counterpart, but also other meaningful information, may be obtained in a chat. For example, information related to an appointment with the counterpart or a schedule may be obtained.

According to an embodiment of the disclosure, the electronic apparatus 100 may obtain schedule information associated with a user of another electronic apparatus in a chat with the user of the other electronic apparatus by using an AI model and store the obtained schedule information in association with contact information of the user of the other electronic apparatus. This embodiment will be described in greater detail below with reference to FIG. 10.

FIG. 10 is a diagram illustrating an example embodiment of the disclosure in which schedule information is obtained in a chat.

Referring to FIG. 10, a user (e.g., user 1) of the electronic apparatus 100 performs a voice chat with a user (e.g., user 2) of another electronic apparatus using the electronic apparatus 100. The electronic apparatus 100 may obtain a name referring to the user 2 in the chat, that is, ‘grill and chicken’, using an AI model, and obtain schedule information (time information). The obtained information may be stored in association with contact information of the user 2 and may be utilized in various functions later.

According to an embodiment of the disclosure, the information obtained in the chat may be stored in association with a time at which the chat takes place. For example, in the case where a voice such as “When did I speak with Bulldog?”, “Who was calling at 3?”, etc. is input, information about the time at which the chat takes place may be used when an AI assistant replies thereto.

A message application or a phone application that provides a chat service also records time information about when a chat took place, and thus the message application or the phone application may be used. For example, information about recent contact records provided by the phone application may be used.

According to an embodiment, when a chat (text chat or voice chat) is performed with a user of another electronic apparatus using the electronic apparatus 100, a contact record with the user of the other electronic apparatus may be added to the recent contact record. In addition, the contact record added to the recent contact record may be tagged with information (a name referring to a counterpart, schedule information, etc.) obtained from the chat. This embodiment will be described in greater detail below with reference to FIG. 11A.

FIG. 11A is a diagram illustrating an example embodiment of the disclosure in which a recent contact record is utilized. FIG. 11A will be described in connection with the chat of FIG. 10.

Referring to FIG. 11A, the electronic apparatus 100 may add time of a chat with the user 2 described in FIG. 10 and a contact of the user 2 to a recent contact record. When the contact of the user 2 is not a previously registered contact, the contact record may be expressed as a phone number (02-1234-9876). Information obtained in a chat, for example, information about a name referring to a counterpart, and schedule information may be added to the added contact record in the form of a tag. For example, as illustrated in FIG. 11A, tag information 1110 may be displayed near the contact record.

According to another embodiment, the information obtained in the chat may be provided to a schedule management application (e.g., a calendar application). For example, information such as ‘grill and chicken’, ‘19:00’, and ‘reservation’ may be included in a schedule of Apr. 20, 2018 in the schedule management application.

According to an embodiment of the disclosure, the electronic apparatus 100 may distinguish whether a chat counterpart is a specific person or a store name, in case of the specific person, store information obtained in the chat in contact information, and in case of the store name, store the store name in the recent contact record in the form of a tag. For example, referring to FIG. 1, when the chat counterpart is the person, the electronic apparatus 100 may store the information obtained in the chat in contact information of a contact application and referring to FIG. 11A, when the chat counterpart is the specific store name, the electronic apparatus 100 may store the information obtained in the chat in the recent contact record in the form of a tag.

The schedule information obtained in the chat may be used in various situations. For example, when a user voice requesting information about the chat counterpart associated with the schedule information obtained in the chat is input, the electronic apparatus 100 may provide a reply message UI including a name referring to a user of another electronic apparatus. This will be described in greater detail below with reference to FIGS. 12 to 14.

The electronic apparatus 100 may search the recent contact record for a contact record having ‘Apr. 20, 2018’ and ‘Grill and Chicken’ corresponding to the time information ‘Next Friday’ obtained from the user voice as tagging information. Referring to FIG. 11A, the electronic apparatus 100 may find a contact record “02-1234-9876” having ‘Apr. 20, 2018’ and ‘Grill and Chicken’ as the tagging information. In addition, the electronic apparatus 100 may perform a call connection to the contact record “02-1234-9876”.

FIG. 14 is a diagram illustrating another example embodiment of the disclosure in which schedule information obtained in a chat is utilized. FIG. 14 will be described in connection with the embodiment described in FIG. 11A.

Referring to FIG. 14, when a voice “Bixby! Text Grill and Chicken reserved on next Friday to delay only 30 minutes of a reservation time” is received from a user, the electronic apparatus 100 recognizes a trigger keyword “Bixby” to activate an AI assistant, obtain time information and a store name, and search for a phone number corresponding to the obtained time information and store name from a recent contact record.

The electronic apparatus 100 may search the recent contact record for a contact record having ‘Apr. 20, 2018’ and ‘Grill and Chicken’ corresponding to the time information ‘Next Friday’ obtained from the user voice as tagging information. Referring to FIG. 11A, the electronic apparatus 100 may find a contact record “02-1234-9876” having ‘Apr. 20, 2018’ and ‘Grill and Chicken’ as the tagging information. The electronic apparatus 100 may confirm that the reservation time is 19:00 from the information tagged in the contact record, calculate a time that the user wants to change, and transmit a text message requesting a reservation change to “02-1234-9876”.

The information tagged in the recent contact record may be deleted together when the contact record is deleted by the user, and may also be automatically deleted together after a retention period of the contact record has passed.

In addition to tagging the information obtained in the chat to the recent contact record, the electronic apparatus 100 may provide the information obtained in the chat to a schedule management application, and a personal assistant may use information in the schedule management application according to a user request to reply to the user.

According to another embodiment of the disclosure, the electronic apparatus 100 may add information obtained in a chat to a contact list. This will be described with reference to FIG. 11B.

FIG. 11B is a diagram illustrating an example contact list UI 1100 provided by the electronic apparatus 100 according to an embodiment of the disclosure.

The electronic apparatus 100 may provide the contact list UI 1100 for contact information stored in the electronic apparatus 100. The contact list UI 1100 may include UI items representing stored contacts. When a UI item is selected, the electronic apparatus 100 may provide a UI including detailed information (a phone number, an email, etc.) of a contact corresponding to the selected UI item.

The electronic apparatus 100 may add information (e.g., a name referring to a counterpart, a keyword indicating a relationship with the counterpart, an address of the counterpart, schedule information related to the counterpart, etc.) obtained from various chat types (e.g., a phone, a text message, a message application, a chat application, an SNS application, etc.) to a contact list. For example, the electronic apparatus 100 may obtain ‘Honey’, which is a name referring to Jane, in a chat with Jane, obtain ‘Bulldog’, which is a name referring to Hong Gil-Dong, in a chat with Hong Gil-Dong, and add the obtained information to the contact list. In this case, as shown in FIG. 11B, the electronic apparatus 100 may provide the contact list UI 1100 including ‘Honey’ 1110 in a UI item of ‘Jane’ and ‘Bulldog’ 1120 in a UI item of ‘Hong Gil-Dong’.

According to another embodiment of the disclosure, when a contact is searched for in the contact list, the contact may be searched even though a name obtained through a chat is searched for, other than an existing name. For example, referring to FIG. 11B, the contact may be searched by inputting a search term in the contact list UI 1100. In this example, when the contact is searched for using ‘Bulldog’ as the search term, a contact for Hong Gil-Dong may be provided as a search result.

FIG. 15 is a diagram illustrating an example embodiment of the disclosure in which a contact is registered in association with an SNS application.

Referring to FIG. 15, the electronic apparatus 100 may search for and register the contact in an address book (or a friend list) of an SNS application (e.g., KakaoTalk™, Facebook™, etc.) but not in a default contact application of the electronic apparatus 100. For example, as illustrated in FIG. 15, a contact for Lee Gi-Baek, which is a person in the friend list of the SNS application but not in the default contact application of the electronic apparatus 100, may be newly registered in the default contact application of the electronic apparatus 100. In this example, items of the contact may be filled in with information provided by the SNS application. For example, a phone number item 1510, an email address item 1520, an SNS ID item 1530, etc. may be filled in based on the information provided by the SNS application.

Meanwhile, not only the contact may be newly registered based on the information provided from the SNS application, but also empty items among items of an existing contact may be filled in. For example, when the contact for Lee Gi-Baek is already registered in the default contact application of the electronic apparatus 100, and an email address item among items constituting the contact for Lee Gi-Baek is empty, the electronic apparatus 100 may receive an email address of Lee Gi-Baek from the SNS application and fill in the email address item.

In addition, the electronic apparatus 100 may obtain information (a name referring to the counterpart, a relationship with the counterpart, a schedule with the counterpart, etc.) related to a counterpart in a chat made through the SNS application, as described above and include the information in contact information. For example, the electronic apparatus 100 may obtain a name ‘Husky’, which refers to Lee Gi-Baek, in a chat with Lee Gi-Baek made through the SNS application, and fill the obtained name in a nickname item 1540 of a Lee Gi-Baek contact of the default contact application.

In this way, the information added to the contact information may be utilized for various functions such as a dialing function, a message sending function, a reply to a user voice inquiry, etc. as described above.

As described above, according to various embodiments of the disclosure, contact information may be newly registered based on information obtained from various chat types or information obtained from various chat types (e.g., a phone, a text message, a message application, a chat application, an SNS application, etc.) may be stored in association with existing contact information, and may be utilized for various functions.
